磷系阻燃剂在透明防火涂料中的应用研究进展

木结构建筑耐火等级低、火灾荷载大，一旦发生火灾将会造成严重的火灾事故，透明防火涂料因兼具优异的装饰性能被广泛用于增强木结构建筑的火灾安全。磷系阻燃剂具有环保、高效、低毒等优点，是透明防火涂料的主要组成部分。从磷酸酯类阻燃剂、磷-氮阻燃剂和复合磷系阻燃剂等方面，综述了磷系阻燃剂在透明防火涂料中的应用研究进展。指出开发出多功能改性磷系阻燃剂，实现磷系阻燃剂三源一体、有机无机复合、多种元素协效阻燃是未来透明防火涂料的发展趋势。

Progress in research and application of phosphorous flame retardants in transparent fire-retardant coatings

Wood-based structure has low fire resistance levels and large fire loads. Once a fire occurs, it will cause serious fire accidents. Transparent fire-retardant coatings are widely used to enhance the fire safety of ancient buildings due to their excellent decorative properties and fire resistance properties. Phosphorus-based flame retardants are widely applied as the main component of transparent fire- retardant coatings due to the advantages of environmental friendliness, high efficiency, low toxicity, etc.. This paper summarizes the research progress of phosphorus-based flame retardants in transparent fire-retardant coatings from the aspects of phosphate ester flame retardants, phosphorus-nitrogen flame retardants and composite phosphorus flame retardant. Research pointed out that the development of multifunctional modified phosphorus flame retardants, the realization of three sources in one, organic and inorganic phosphorus flame retardants, and the synergistic flame retardancy of multiple elements are the development trend of transparent fireretardant coatings in the future.
